Title: Improvements in machine tools
IPC: B23Q5/40
Filed: 1929-08-01
Abstract: 342,664. Indicating-apparatus. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE, 8, Rue des Vieux-Grenadiers, Geneva, Switzerland. Aug. 1, 1929, No. 23666. Convention date, Oct. 13, 1928. Void [Published under Sect. 91 of the Acts]. [Class 106 (iv).] The movements of a screwactuated work table or tool slide on a lathe, milling or boring machine &c., are indicated by a second screwed shaft in threaded engagement therewith and connected to the drive screw by transmission gearing capable of transmitting only a limited torque, so that the measuring screw is relieved from the wear of acting as a driving member. The drive screw c and measuring screw d, mounted in bearings on a bed b, respectively engage nuts s, r secured to the table &c. a slidable on guideways, the measuring screw being provided with a graduated head e from which the indications are read. The driving-gear comprises a crank-driven pinion p meshing with a pinion h, transmitting the drive to the screw c through a lost-motion connection i, j, and also transmitting rotation to a pinion l frictionally mounted between discs m<1>, m<2> pressed together by a spring n on the measuring screw d. In virtue of the lost-motion connection i, j, the first action, upon rotation of the crank q, is to move the threads of the screw d into contact with those of the nut r, the friction coupling then slipping until the screw c takes up the drive. To compensate for imperfections in the threads &c., the gear ratios and screw pitches may be so arranged that the screw d constantly tends to move the table slightly more rapidly than it is actually moved by the screw c, continuous slip of the friction coupling occurring in this case.

Filed: 1945-09-14
Abstract: 604,604. Course recording apparatus. EMERY, J. N. Sept. 14, 1945, No. 23825. [Class 97 (ii)] A position indicator for an air or other craft comprises a stationary location representation of a locality such as a runway and its approach path and a mechanical element representing the craft mounted for translational and rotation movement in response to applied electrical signals so as to indicate the instantaneous position and heading of the craft in relation to the locality represented. As shown a landing ground and the funnel of approach of a beam approach beacon system are represented by fixed wires 2, 3. An aircraft model 5 is rotated about an axis AB by a compass repeater 11 to indicate the heading of the aircraft. The repeater 11 is adjusted about the axis CD and the model 5 moved up and down the slot 9 in the panel 8 accordingly by a motor controlled by the range signal. The frame 7, carrying the panel 8 and the pivot axis CD, is itself adjustable about a vertical axis EF by a motor controlled by the azimuth beam signals. The range and azimuth motors may be of the selsyn controlled type arranged in potentiometer balanced circuits so that the motors are controlled in a follow-up manner. The model 5 thus moves relatively to the wires 2, 3, so as to indicate continuously the position of the aircraft relative to the landing ground. Stops may be provided to limit the rotation about the axes CD and EF. A glidepath indicator 4, projecting through a slot 9a in the panel 8, is connected to the armature spindle of a moving coil meter 12 and is thereby moved under the control of radio signals to indicate the position at which the aircraft will touch down.

Title: Improvements in and relating to slitting and reeling paper and the like
IPC: B65H18/26
Filed: 1927-09-10
Abstract: 304,158. Jones, A. J., Nicholas, F., and Robinson, Ltd., E. S. & A. Sept. 10, 1927. Winding w e b s ; collapsable spindles and rollers. - In a machine for slitting and rewinding a web of paper or the like, the slit web is rewound on a spindle which is mounted on a stationaxy axis and is directly driven, and the slitting-discs and their hardened steel or like backing-roller are carried by a counterweighted displaceable frame, so that the roller, around which the web is passed, is pressed against the growing reel with a substantially constant pressure. The device is particularly applicable to a machine for subjecting a web of paper to a glazing or waxing process for the production of bread-wrapping paper. The paper as it comes from the machine passes round a roller 31, whereon it is cut into strips by discs 32, to a rewiuding-spindie 9. The roller 31 and discs 32 are supported on a frame 30 pivoted at 33 and weighted so that the roller 31 is continually pressed against the spindle 9, but can swing downward as the diameter of the rewound xoll increases. The counterweight on the frame is adjustable to enable the correct pressure to be imposed on the roll. The discs 32 are carried in arms 36 carried by brackets 37 secured to a shaft 38 mounted on the frame, and adapted to be swung over by a handle 42 into operative or inoperative position. According to the Provisional Specification, a hand-operated cam may be provided for this purpose. An adjustable spring 40 regulates the pressure of the cutting- discs. The discs and spindle 9 engage the roller 32 in close proximity, being preierably less than half the circumference of the roller apart. The spindle is held against longitudinal. movement and is driven by gears 12, 13 and a frictionclutch 10 adjustable by a hand-wheel 11. The spindle is held against longitudinal movement in its bearings by collars 24, 26, by thrust-ball races, or by a thrust plate at one end and a groove engaged by an adjustable fork at the other end. The spindle is formed with a number of inclined portions 15 which are engaged by wedges secured to a tube 17 split into a number of parts. The ends of the tubes 17 are received in recessed collars, one of which 20 screws on to the spindle to effect longitudinal movement of the tube and to cause it to expand and grip the spool on which the paper is wound. The other collar 21 is held in position by a spring 22. The marginal portions of the web are removed, but in order to prevent the narrow margins from becoming entangled in the machine or with other parts of the web, the outer discs 32 are formed with a notch or notches in their cutting-edges so that the margins are not completely severed.

Title: Process for the manufacture of alumina enabling the use of the low blast-furnace
IPC: C01F7/38
Filed: 1957-07-29
Abstract: Alumina is obtained from siliceous bauxite by heating said bauxite together with carbon and iron pyrites in a low blast furnace to which a blast of oxygenated air is admitted to maintain a zone at 1750-1850 DEG C. in the furnace, through which the charge passes to form a molten Al2O3-Al2S3 slag and a ferro silicon alloy, separating said slag from said alloy and hydrolysing the aluminium sulphide therein. The product is a mixture of crystalline and amorphous alumina.  In the example, dilute hydrochloric acid was used for hydrolysis.  If desired iron may be added to the charge to retain in the furnace sulphur liberated in the lower parts thereof.  The bauxite may be presulphurised with sulphur-containing gases, e.g. hydrogen sulphide, by bringing the bauxite into contact in a separate plant with gases evolved from the furnace; thereafter the purified gases may be burnt and the combustion products used to preheat the furnace blast.ALSO:Ferrosilicon is produced inter alia in the production of alumina, by heating siliceous bauxite together with carbon and iron pyrites in a low blast furnace to which a blast of oxygenated air is admitted to maintain a zone at 1750-1850 DEG C. in the furnace, through which the charge passes to form a molten Al2O3-Al2S3 slag (which is separated for processing) and ferrosilicon.  The blast preferably contains 50-70% by volume of oxygen.  If desired iron may be added to the charge to retain in the furnace sulphur liberated in the lower parts thereof.  The bauxite may be presulphurized with sulphur-containing gases, e.g. hydrogen sulphide, by bringing the bauxite into contact in a separate plant with gases evolved from the furnace; thereafter the purified gases may be burnt and the combustion products used to preheat the furnace blast.

Abstract: 797,783. Heating air. OXY-CATALYST, Inc. Aug. 7, 1956, No. 24225/56. Class 64(3) [Also in Group XXVII] A heat exchanger in which air is heated is arranged in a casing 6 in radiant heat relationship to a catalyst bed 15a over which the exhaust gases from an I.C. engine are passed to raise the temperature of said gases and said catalyst bed. In the form shown, in which the heat exchanger heats air for supply to a vehicle space, the catalyst bed 15a, Fig. 2, separates two chambers A, B respectively in the casing, the bed being confined between two foraminous trays 13, 14, e.g. of stainless steel. The air heater is disposed in the lower chamber B but may be located in the upper chamber A and may comprise a Field tube, Fig. 6 (not shown), or, as shown, a plurality of U- shaped tubes 18 the ends of which are secured to a suitably partitioned header 19. Air passes to and from the header 19 by way of inlet and outlet conduits 24, 25 which can be interconnected by a valvecontrolled by-pass causing more or less fresh air from the conduit 24 to by-pass the heater whereby the temperature of the air passing to the outlet conduit 25 and hence to the vehicle space may be regulated. The air heater receives heat both by radiation from the catalyst bed and from the exhaust gases as they pass over the tubes 18 to the casing outlet 7a. A venturi inspirator 5a is provided to mix fresh air with the exhaust gases prior to their entry into the chamber A, the inspiration of air being regulated to compensate for fluctuations in the temperature and rate of flow of the exhaust gases thereby to provide a uniform supply of heat regardless of engine speed. The catalyst bed 15a comprises pellets of activated metal oxide such as aluminium, zirconia, beryllia or mixtures thereof, impregnated with metallic platinum, palladium or combinations such as copper-chromium. Fig. 7 shows an arrangement suitable for use with a diesel engine.

Abstract: 278,686. Bosch Akt.-Ges., R. Oct. 8, 1926, [Convention date]. Cam-actuated pumps; regulating by opening bypasses and suction valves, valve gear for and drip preventing in.-In a liquid fuel admission device in which liquid fuel is supplied by a pump which allows a small amount of fuel to flow back at the end of its stroke to prevent drip at the nozzle 13, a non-return valve 7 closes in the event of leakage of cylinder gases past the valve 13. The valve 7 is prevented from closing during normal working by the provision of a square thread 11, or fine, longitudinal or transverse, ribs, on a piston like extension 10 which slides in a barrel 5, mounted either horizontally or vertically and loaded by a spring, and this allows the back-flow of fuel to take place. The pump shown in Fig. 1 comprises a plunger 19 actuated against a spring 18 by a cam 17, and a spring-pressed delivery valve 20, which is held open mechanically by the plunger 19 at the end of its stroke to cause the back-flow in the delivery pipe 12. The suction valve 21 is operated by a cam 22 through a tappet rod in two parts 23, 24, screwed together for adjustment in length. In the alternative form of pump, shown in Fig. 3, a by-pass 34 allows fuel to flow back when its base 33 is connected to the suction pipe 35 by an annular space 32 in the pump plunger 30. The upper face of the space 32 is bevelled as shown, and rotation of the plunger enables the amount of the fuel flowing back to be varied.
